Obtaining the manual sources

The Docbook XML sources of the documentation are hosted on php.net's
SVN server in the peardoc module.

The checkout process is relatively simple:

$ svn checkout https://svn.php.net:/repository/pear/peardoc/trunk

Details about this process as well as anonymous login data can be
found on php.net's SVN
page.

You need rights for the peardoc SVN module to
be able to commit. Along with pear karma, every developer should have
gotten the appropriate rights to peardoc. This is how
it should be in theory, but one will probably have to send a mail to
pear-dev@lists.php.net asking for documentation karma.
